    Are We Fast Yet? Comparing Language Implementations with Objects, Closures, and Arrays

    I did some measurements recently with 3.0.0 RC1 compared to 2.1.0 based on https://github.com/smarr/are-we-fast-yet. Here are the results: http://software.rochus-keller.ch/are-we-fast-yet_crystal_rub.... Ruby 3.0 without JIT is factor 1.2 faster than Ruby 2.1.0; Ruby 3.0 with JIT is only factor 1.4 faster than Ruby 2.1.0. Crystal is about factor 20 faster.

  • normandy

    Channels for CSP style Ruby

    Do learn Ruby. You seem to answer your own question! You’re curious about it, worst case you’ll have opened your mind to something else which is only a good thing.

    But do not be fooled by Rails, Ruby is quite something else, of which Rails is a very small, opinionated part.

    Tips: look at MiniTest source code, Sinatra and Rack source code are quite interesting too.

    Shameless plug, a couple of idiomatic Ruby repos of mine:

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Data Platform where developers build real-time applications for analytics, IoT and cloud-native services in less time with less code.

  • Async Ruby

    An awesome asynchronous event-driven reactor for Ruby. (by socketry)

    in ruby you have the async gems from https://github.com/socketry/async

    i dont know for data manipulation but i guess also ruby has it. maybe this https://github.com/thbar/kiba

  • PyCall.jl

    Package to call Python functions from the Julia language

    Can recommend, it's pretty elegant, fun, and efficient. Also: https://github.com/JuliaPy/PyCall.jl "This package provides the ability to directly call and fully interoperate with Python from the Julia language."

  • fast-ruby

    :dash: Writing Fast Ruby :heart_eyes: -- Collect Common Ruby idioms.

    If you’re interested in speed, check this repo: even among Ruby idioms there are big speed differences.

  • gleam

    ⭐️ A friendly language for building type-safe, scalable systems!

    Have you seen Gleam Lang? It's like Haskell but on BEAM. I was looking into it but I decided that since there's next to no ecosystem for it, I might as well go with something like Rust.

  • crystal

    The Crystal Programming Language

  • Scout APM

    Truly a developer’s best friend. Scout APM is great for developers who want to find and fix performance issues in their applications. With Scout, we'll take care of the bugs so you can focus on building great things 🚀.

  • mongo_orm

    Mongo ORM: A simple ORM for using MongoDB with the crystal programming language, designed for use with Amber. Based loosely on Granite ORM. Supports Rails-esque models, associations and embedded documents.

    > If you're not, you can port to anything and it'll be roughly equivalent and having a static language in Ruby's clothes doesn't scratch much of an itch.

    There are a couple of reports about successful ports, e.g. https://forum.crystal-lang.org/t/experience-porting-a-ruby-w....

    > I don't see a great argument for using Crystal in 2020

    There is still the Ruby-like syntax appreciated by many developers and Crystal has also some other interesting aspects not present in Ruby or imperative OO languages in general, e.g. union types, powerful macros (see e.g. https://github.com/sam0x17/mongo_orm/blob/master/src/mongo_o...).

  • csharplang

    The official repo for the design of the C# programming language

    Its current support in .NET Core and closed issues with won't fix.
